More Mendel Problems

The problems continue... The new hot end parts arrived, and were fine, but i couldn't get the old heater resistor out of the heater block. So i ordered a new cartridge heater, which is the replacement for the resistor. I fitted that this morning and wired it up. heating up the hot end, I saw the temperature reach 150C or so then drop back. Measuring the cartridge heater found it to be 350k, so essentially open circuit. I'll have to get a replacement...

Looks like the new Duet electronics that are on the Fisher printer can be retro fitted to the mendel, so I'll see how that goes and maybe do a retro fit later. That'll solve the problems I'm having installing host software on older hardware.
